53236145 divided by 266 
Let's see how many times 266 fits into 53236145.

Moving on to step 1:
5 divided by 266 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 266

Advancing to step 2:
When dividing 53 by 266, we get 0 with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Grab the next digit (2) from the dividend, add it to 53, then carry on: 532 / 266

Step 3:
266 goes into 532 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 532 from 532, we get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 266

Moving on to step 4:
3 divided by 266 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 20.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 266

Step 5:
If we divide 36 by 266, we get 0 and a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 200.0
The remainder is 36 after subtracting 0 from 36.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 266

Let's proceed to step 6:
266 can be fit into 361 1 times, resulting in a remainder of 95.
Put 1 as the next digit of the answer. 
Result so far: 2001.0
The remainder is 95 after subtracting 266 from 361.
Append the next digit (4) from the dividend to 95 and continue with: 954 / 266

Advancing to step 7:
The number 266 fits into 954 3 times, leaving a remainder of 156.
Use 3 as the next digit of our solution. 
Result so far: 20013.0
If we subtract 798 from 954, we get 156.
Grab the next digit (5) from the dividend, add it to 156, then carry on: 1565 / 266

Going ahead to step 8:
If we divide 1565 by 266, we get 5 and a remainder of 235.
Put 5 as the next digit of the answer. 
Result so far: 200135.0
Subtracting 1330 from 1565 leaves us with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Going ahead to step 9:
266 goes into 2350 8 times with a remainder of 222.
Write down 8 as next digit of the result. 
Result so far: 200135.8
If we take 2128 away from 2350, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 10:
The number 266 fits into 2220 8 times, leaving a remainder of 92.
The next digit of our result is 8. 
Result so far: 200135.88
Subtract 2128 from 2220 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Our division results in 200135.88 with a remaining 0.092.
